Extending thl gjlghjtlie' by 5 pl end bent and extended into the hole 31 of the arm 30. At its upper end it is provided with two right angular bends, as indicated at 45, and its extremity bent to engage a hole in the detent 36, said hole being located intermediate between the ends of said detent. The upper end of the rod 44 is bent and extended into the hole 32 of the arm the lower end being oilset and its extremity bent to engage a hole 47 in the oflset portion 41 of the detent 37. By constructing the detents and operating rods as above described, only a very small space is required for the passage of the rods, and ample clearance is provided for the detents without marring the appearance of the door.

For the purpose of locking the slidable member 26 against movement, any desired locking device may be employed. In the drawing, is conventionally illustrated a well known form of lock consisting of a rotatable tumbler barrel 50, which is provided at its inner end with an actuator 51 having a peripheral enlargement 52 forming oppositely disposed shoulders. Said shoulders are positioned to engage pins 53 projecting from a locking member 54, rotatable upon said barrel. By inserting a key through a suitable slot in the barrel and turning the same, the shoulder 52 engages one or the other of the pins 53 and raises the locking member to a position in the path of movement of the lower end of the slidable member 26, and prevents retraction thereof against the tension of the spring 27. (See full lines, Figure 4). By reversely operating the member 51, the member 54 is allowed to drop as shown in dotted lines, Figure 4, thereby leaving the member 24 free to slide.

In operation, the parts are so mounted upon the edge of the door stile that when the door is moved to closed position the detents 36 and 37 will engage keeper plates in the door frame in a manner well understood in the art. As the door is closed, the detents are rocked upon their respective pivots, moving the rods 43 and 44 downwardly and imparting a corresponding movement to the arm 30 and the slidable member 26, against the tension of the spring 27. It will be particularly noted that by connecting the wire 43 with the middle portion of the detent 36, and the rod 44 with the end of the detent 37, pivotal movement of said detents in opposite directions will impart movement to the arm 30 and slidable member 36 in a common direction, i. e. against the tension of the spring 27. When it is desired to open the door, the operator places his finger into the depression 18 and grasps the ring-like portion 21 of the actuator 22, swinging said ring-like'end outwardly upon the pivot 21, and through th engagement of the lugs 24 and 25, forcing the slidable member 26 downwardly against the tension of the spring 27. This movement exerts a pull upon the wire 43 and a push upon the wire 44, thereby moving them both in a common direction and rocking both detents to disengage the hook portions 42 from the complemental plates in the door frame. A

continued pull upon the ring-like portion 19 in the same direction will result in swinging the door upon its hinges. If it is desired to lock the door in closed position, a key is inserted in the barrel 50 and the member 51 rotated so as to lift the lock member 54 upwardly to the position shown in full lines in Figure 4. lVhen so positioned, said member 54 acts as an abutment to prevent longitudinal movement of the slidable member 26, and the door is therefore firmly locked in its closed position. Then it is desired to unlock the ooor, the member 52 is rotated so as to bring the member 54 to the position shown in dotted lines Figure 4, allowing" ample clearance for the slidable movement of the lower portion of the member 26. i

In lieu of the two rods or wires 43 and 44, a single wire may be employed, as illustrated in Figure 6, Referring to said figure, designates a. wire having a spread portion 1 riveted to the arm 30. The endsof said wire where they are connected with the detents should be shaped to correspond to the shapes of wires 43 and 44 at the same po sitions. i

The advantages of the invention will be readily apparent to those skilled in the art to which it belongs. It will be particularly noted that a simple means is provided by which locking detents may be conveniently positioned at'the ends of a door stile and simultaneously operated from an intermediate point by means of a common actuator. Because of this arrangement, it is not necessary to out very deeply into the stile of the door'to provide the necessary clearance for the detents and the operating rods, and this is a particular advantage in connection with the doors of show cases and similar structures where relatively thin stock is employed. It

is to be understood, however, that the invention is not limited to this particular .class of doors. A further important advantage is thattheopposite pivotal movement is imparted to the slidable member, so that parts may be made to operate in a minimum of space. A further advantage is that simple means are provided by which a continued pull in one direction will first unlock the door and then move it to open position. By placing the guide strip over an angular cutaway portion of the stile, a simple guide is provided which gives a neat finish andyet at the same time, all of the working parts associated with the detents, are readily accessible. I t v Having thus explained the nature of the invention and described an operativemanner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what is claimed is 1. The combination with a door having a recess in one of its stiles and a portion of the edge of said stile provided with a longitudinally disposed angular portion, and removable cover strips of angular cross section cooperating with said angular portion to provide guide-Ways, of a carrier plate covering said recess and provided with a slidably I mounted operating member extending into the recess, locking detents located at the top and the bottom of said stiles adjacent the ends of said guide-ways, links located in said guide ways and independently connecting said detents with said arm so that they may move in unison therewith, a spring acting to retain said operating member in a predetermined normal position so as to hold said detents in a normal locking position, andan actuator engaging said operating member, said actuator being so connected that the door will first be unlocked and then moved to open position by a continued pull upon said actuator in one direction.

2. The combination with a movably mounted door, of a rectilinearly movable operating member supported thereby, detents pivoted to said door and spaced from said operating member in opposite directions, a link connection between said detents and said operating member, spring means acting to retain said operating member in a predetermined normal position so that said detents are maintained in their normal locking positions, and an actuator for imparting movement to said operating member in opposition to the tension of the spring means, said actuator being so connected that the door will first be unlocked and then moved to open position by a continued pull upon said actuator in one direction.
